This study focuses on the role of institutions and organizations in the development of corporate finance from the Italian merchant banks of the Renaissance through the formation of conglomerates and leveraged-buy-out partnerships in contemporary Wall Street. It also puts forth a compelling argument for the closer integration of historical and quantitative research methodologies in financial theory. The epilogue contains an original algorithm that explains the relationship between the short-term, firm-specific factors and longer-term environmental elements that have shaped the historical development of finance.
